论文摘要
与可见扇区有微弱相互作用的暗物质（DM）可以通过与弱相互作用的大型粒子（WIMP）进行实质性相互作用来进行热度。这样的DM候选者被归类为伪金条（PFIMP）。 PFIMP可以通过WIMP循环提供直接和间接搜索的前景。这项工作着重于这种可能性。我们提供了涉及标量，费米和矢量玻色子颗粒的所有此类环形图，PFIMP可以通过$ \ Mathbb {Z} _2 \ otimes \ Mathbb {Z} _2 _2 _2^{\ prime} $ symmeties与标准模型相互作用。我们详细阐述了一个模型，即Fermion DM充当WIMP和标量单元，充当PFIMP，具有可以忽略不计的Higgs门户相互作用，并且通过Yukawa的相互作用进行了实质性转换。我们详细研究了循环在模型允许的遗物密度区域中诱导的直接和间接搜索前景。
A dark matter (DM) having feeble interaction with the visible sector can thermalise via substantial interaction with a Weakly Interacting Massive Particle (WIMP). Such DM candidates are categorised as pseudo-FIMP (pFIMP). pFIMP can provide both direct and indirect search prospects via WIMP loop. This work focuses into such possibilities. We provide all such one loop graphs involving scalar, fermion and vector boson particles via which pFIMP can interact with the Standard Model assuming both of them are stabilised via $\mathbb{Z}_2\otimes \mathbb{Z}_2^{\prime}$ symmetries. We elaborate upon a model where a fermion DM acts as WIMP and a scalar singlet acts as pFIMP having negligible Higgs portal interaction and substantial conversion via Yukawa interaction. We study in details the loop induced direct and indirect search prospects of the pFIMP in the relic density allowed region of the model.
